Preferentially, the functional recess has different functions depending on a fitting-in state of the plate base body. Preferably the implant plate device is realized by a bone plate. Different implementations of a bone plate, deemed expedient by someone skilled in the art, are conceivable, like for example as a neuro-surgical bone plate. However, preferentially the bone plate is implemented by an orthodontic bone plate, like in particular a mentoplate, a uniplate and/or an alveolar plate.

In particular, an advantageously positionally accurate and angle-accurate introduction of the implant plate device on a jaw is achievable. It is furthermore possible to provide an implant plate device that is introducible in an advantageously simple manner. Moreover, in particular an advantageously modular utilization of the implant plate device is achievable. In particular, depending on a usage, different orthodontic treatment apparatuses may be coupled releasably with the implant plate device. In particular, over a treatment period, different orthodontic treatment apparatuses can be used consecutively with the same implant plate device. It is in particular possible to do without additional jawbone screws. Furthermore, in particular a firm anchoring in the bone is achievable by means of the implant plate device. This in particular enables advantageously high traction, like for example for a distalization of the molars.
It is further proposed that the implant plate device comprises at least one inner thread which adjoins the functional recess and is configured for an angle-stable coupling with an orthodontic treatment apparatus and/or with a drilling and/or insertion templet. Especially preferentially the functional recess may be configured for an angle-stable coupling with a drilling and/or insertion templet, as well as for a later coupling with an orthodontic treatment apparatus. The inner thread is in particular configured for a screwing coupling of the orthodontic treatment apparatus and/or of the drilling and/or insertion templet with the functional recess. In particular, the orthodontic treatment apparatus and/or the drilling and/or insertion templet can be screwed into the functional recess. This in particular allows achieving an advantageously simple and secure coupling of different orthodontic treatment apparatuses and/or drilling and/or insertion templets. In particular, a releasable coupling is achievable.
Furthermore it is proposed that the implant plate device comprises a further fixing recess, which is introduced in the plate base body, which is arranged on a side of the functional recess that is situated opposite the fixing recess and which is configured for receiving a jawbone screw that is configured, for a fixation of the implant plate device, to be screwed through the fixing recess into a bone, in particular a jawbone, and which comprises at least one inner thread adjoining the further fixing recess. Preferably the fixing recess and the further fixing recess are in each case arranged neighboring the functional recess. Preferentially the fixing recess, the further fixing recess and the functional recess extend in each case through the plate base body perpendicularly to a main extension plane of the implant plate device. The extension axes of the fixing recess, the further fixing recess and the functional recess preferably extend in each case perpendicularly to a main extension plane of the implant plate device. The extension axes of the fixing recess, the further fixing recess and the functional recess are in particular arranged in a common plane. Preferably the extension axes of the fixing recess, the further fixing recess and the functional recess in each case correspond to a bore axis and/or a rotational symmetry axis of the respective recess. By a “main extension plane” of a structural unit is in particular a plane to be understood which is parallel to a largest side surface of a smallest imaginary rectangular cuboid just still completely enclosing the structural unit, and which in particular runs through the center of the rectangular cuboid.

This in particular allows providing an advantageously compact implant plate device.
Beyond this the invention proposes an implant system with an implant plate device according to one of the preceding claims and with at least one jawbone screw which is configured, for a fixation of the implant plate device on a bone, in particular a jawbone, to be screwed through the fixing recess into a bone, in particular a jawbone. It is further proposed that the at least one jawbone screw comprises at least one first thread for screwing into a bone and at least one second thread for screwing into the inner thread of the implant plate device that adjoins the fixing recess, wherein a thread pitch of the first thread differs from a thread pitch of the second thread. Preferably the jawbone screw has at its head a thread that is respectively configured to be screwed into an inner thread of the fixing recess of the implant plate device. Preferentially, the thread of the head of the jawbone screw has a pitch that differs from the main thread of a threaded shaft of the jawbone screw. Preferentially, the different thread pitches will result in maintaining the distance for a lifting or a pressing to the mucous membrane or to the bone. The first thread is in particular implemented by a self-drilling or self-cutting bone thread whereas the second thread is implemented by a special head thread engaging into a respectively matching thread in the implant plate device in such a way that an angle-stable connection is created in a certain angle range between a longitudinal implant axis and a longitudinal thread axis. The second thread of the jawbone screw is in particular characterized in that, during insertion in the jaw, it engages into the inner thread of the implant plate device in such a way that a force-fit and torque-fit connection is created at the end of the insertion process. This allows dispensing with additional connection elements. Optionally the screwhead may be equipped with an additional thread within its head region for receiving further elements. In this way it is in particular achievable that the jawbone screw enters a fix connection with the fastening unit and with the expansion unit, resulting in a secure three-dimensional construction.
It is also proposed that the thread pitch of the second thread of the jawbone screw is greater than the thread pitch of the first thread of the jawbone screw. Particularly preferentially the thread of the head of the jawbone screw has a greater thread pitch than the thread proper of a threaded shaft of the jawbone screw. In this way, by turning the thread at the head of the jawbone screw into the implant plate device, a subsequent lifting of the implant plate device and thus a lifting of the patient's mucous membrane is achievable. In addition, it would be conceivable, with a corresponding implementation of the inner thread of the implant plate device and/or of the thread of the head of the jawbone screw, to achieve, in a limited way, a multi-directional alignment.

The drilling and/or insertion templet is in particular supported on at least one, in particular on at least three or more, dental occlusion surfaces. The alignment element preferably comprises on at least one side a tooth surface contour for an unambiguous positioning on a tooth. Preferably the alignment element is in particular configured for a positionally accurate support on a tooth, in particular a molar. The alignment element in particular serves for a positioning and support of the drilling and/or insertion templet in a jaw. It would moreover be conceivable, for example, that the at least one alignment element is connected to a tooth temporarily by gluing, for the purpose of avoiding a slipping of the drilling and/or insertion templet. By an “alignment element” is in particular, in this context, an element to be understood via which an operator can position the drilling and/or insertion templet relative to a jaw in a defined manner. In particular, the alignment element has a defined, unambiguous relational position in an oral cavity. The alignment element is in particular manufactured at least partly individually and is adapted to the defined unambiguous relational position in the oral cavity. By a “fixing element” is in particular, in this context, an element to be understood via which the drilling and/or insertion templet can be connected to the implant system, in particular the implant plate device, directly. In particular, the fixing element is configured to be connected to the implant plate device by means of a screw and/or plug connection. The fixing element is in particular configured to create a releasable connection to the implant plate device.

By means of a fixation screw passed through the counterbore, the drilling and/or insertion templet is in particular connectable to the implant plate device in a rotationally fixed manner. The alignment elements which are embodied as occlusal supports are in particular connected to the central fixing element via a frame structure. In this way, it is in particular possible to achieve an advantageously secure and positionally accurate mounting of the implant system on a jaw. In particular, prior to pre-drilling and screwing-in of the jawbone screws, the implant plate device can be positioned on the jaw in a defined manner. Furthermore, in particular an advantageously stable and precise support of the drilling and/or insertion templet on a jaw is achievable.
It is further proposed that the drilling and/or insertion templet comprises at least one guiding cylinder, which is firmly connected to the fixing element, for guiding a pre-drill and/or an insertion instrument for the jawbone screw. The guiding cylinder is in particular implemented of a hollow cylinder. Preferably, the guiding cylinder is in particular implemented by a guiding sleeve for an angle-preserving guiding of a pre-drill and/or of an insertion instrument for the jawbone screw. This in particular allows achieving angle-preserving screwing of the at least one jawbone screw, in particular relative to the at least one inner thread of the implant plate device. By a “guiding cylinder” is in particular, in this context, a hollow-cylindrical element to be understood that is configured for axially guiding a pre-drill and/or an insertion instrument and/or of a jawbone screw. Preferably the guiding cylinder is configured to align a rotation axis of the pre-drill and/or of an insertion instrument and/or of a jawbone screw relative to the implant plate device. In particular, the guiding cylinder is configured to align a rotation axis of a pre-drill and/or of an insertion instrument and/or of a jawbone screw perpendicularly to a main extension plane of the implant plate device. By the at least one guiding cylinder, in particular an advantageously precise, in particular angle-preserving, screwing of the at least one jawbone screw is achievable.
It is further proposed that the at least one alignment element is integrally connected to the fixing element. In this way in particular an advantageously accurate and stable drilling and/or insertion templet is achievable. It is moreover possible to keep a number of structural components low. Preferably the entire drilling and/or insertion templet is embodied in a one-part implementation. Preferentially the drilling and/or insertion templet is produced at least partly, in particular completely, in an additive manufacturing procedure, in particular in a 3D-printing procedure. Herein it would in particular be conceivable that only the alignment elements are produced individually, adapted to a patient, and are connected to a standardized fixing element. It would however also be conceivable that the entire drilling and/or insertion templet is produced individually. “Integrally” is in particular to mean connected at least by substance-to-substance bond, for example via a 3D-printing process, a welding process, a gluing process, an injection-molding process and/or another process that is deemed expedient by someone skilled in the art, and/or advantageously formed in one piece, like for example by manufacturing from a cast and/or by manufacturing in a one-component or multi-component injection-molding procedure, and advantageously from a single blank.
The invention is furthermore based on a method for producing the drilling and/or insertion templet. It is proposed that the drilling and/or insertion templet is produced, so as to be individually adapted to a shape of a jaw and/or tooth, in an additive production method, in particular in a 3D-printing procedure. The drilling and/or insertion templet is in particular produced from a synthetic material in an additive manner. This in particular allows providing a drilling and/or insertion templet that is individually adapted to a shape of a jaw. In particular, an optimum individual positioning of the drilling and/or insertion templet in a jaw is achievable.
